T0 aZZ whom it may. concern 1 Be. it. known that we, RO AND H. Lace and CARL W. BIERIG," citizens of the United States, residing atJoplin, in the county of Jasper and State of Missouri, have invented new and useful Improvements in Automatic Slide Advertising Machines, of which the following is a specification.

pictures or other like matter on screens from 1 slides and especially relates to improve. ments' in that class of such machlnes in which the slides are moved successively by a carrier element past the lenses, thevobject. of the inventionbeing to provide an 1m-= thus avoiding the use of a shutter andof shutter operating mechanism' and also enabling' the machine to project advertlsements, pictures or the like in more rapidly than heretofore.

The invention consists in the construetion, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :Figure 1 is partly a sectional view and partly an elevation of a projecting machine constructed in accordance with our invention. Fig. 2 is partly an elevation and partly a sectional view of the same one plane at right angles to that of Fig. 1. Figs. 345 are.

detail views.

For the purposes of this specification a suitable casing is indicated at 1 and the carrier which carries the slides 2 is shown as a wheel 3, the shaft 4 of which is mounted in bearings in suitable standards 5 which are arranged in the casing. The usual funnel is indicated at 6 provided with the condenser and the projecting lenses 8 and an electric lamp for use in projecting the slides i indicated at 9. The slide carrying wheel 3 is provided at one end with a stop disk 10 which is concentric therewith and is provided with a series of appropriately spaced stop openings 11, the latter being arranged in radial alinement with the slides and a stop opening being provided for each slide,

AI stop lever 12 is also provided which is pivotally mounted as on the stop lever to keep'the latter in such This invention relates tonnprovements 1n projecting machines such as magicilanternsand the like for projecting advertisements,-

posltion as to normally keep its pin in engagement wlth one of the stop openings and thus hold the carrier wheel with one of its slides in operative position with relation to the projecting apparatus. The said stop lever has an arm 16 which is provided with a cam face 17 on one side of its free end.

The shaft4 of the slide carrying wheel is also provided with an operating wheel which is here shown as a ratchet Wheel 18 which has peripheral teeth 19 that correspond in number with the stop openings 11 of the 'stop-diskand with the slides on the carrier Wheel. A rod 20 is also provided which'is suitably mounted for reciprocating movement-and is provided at its upperwend With apivoted dog 21 and with a spring 22 which presses against the dog and engages the latter with one of the ratchet teeth when the rod is moved upwardly. A lever 23 is as at 24 and is pivotally connected as at 25 to the operating rod 20. A spring 26 is also provided, which is here shown as a coiled retractile spring which has its lower end secured to the lower end of the rod 20 as at 27 and has its upper end connected to a suitable fixed support 28.

A commutator drum 29 is also provided the shaft 30 of which is here shown mounted in bearings in a casing or frame 31. This commutator drum is driven by a motor of any suitable type or construction, an electric motor 32 being here shown for the purposes of this specification. The commutator drum is provided at one end with a radial tappet arm 33 which carries a tappet roller 34 which is for engaging the cam face 17 of the lever 12 and operating said lever once during each rotation of the commutator drum and on one end of the shaft of said drum is an arm 35 which is adjustably secured as by means of a set screw 36 and is provided at its free end with a tappet roller 37 for engaging the lever 23 and causing the latter to actuate the rod 20.

The commutator drum is provided with a peripheral conductor 38 which in practice is a brass or copper cylinder having an opening 39. A pair of copper or othersuitable contdet erusfiee-oere axed-previewed beeron the peripherfi of tli'e eomumtordmm and which are connected, by V conducting Wires 41 in electric circuit witfithe' 9.
